that link is not valid...

Saltlick, a 630 oring chain is what came standard on my bike.

kghost, I was not talking about the springs on a truck. I was talking about the frame itself.

kghost · « **Reply #27 on:** August 07, 2005, 05:49:40 PM »

Frame by itself doesn't fatigue. Put a bed on it and run it around sure. Won't fatigue just sitting. needs outside stimulus.

eldar · « **Reply #28 on:** August 07, 2005, 05:55:56 PM »

Trust me I know fatigue requires an outside force, but cant gravity supply that? When your chain is on your bike, why does it sag at all? Gravity. After enough time of even having to support its own weight, a chain will stretch.

All I can say is what I have seen myself. Everyone has their opinion. It is like the "are ghosts real" arguement.
I have seen the effects of metal fatigue on something not used.

kghost · « **Reply #29 on:** August 07, 2005, 06:01:17 PM »

Yeah, Like in about 4 million years. Now, If you let it corrode you can fatigue and break stuff much faster. Same with thermal cycles (heating and cooling).

Based on your premise, steel reinforced buildings are about to topple from the force of gravity.
Go put a steel rod on a shelf and see how long gravity takes to break it in half.

Guess you should stay away from old NOS parts. Gravity has been affecting them all these years. Just box any you have and send'm to me.

eldar · « **Reply #30 on:** August 07, 2005, 06:03:45 PM »

Thats why I would not use NOS chains or sprockets for that matter, why use something that was weak years ago.

So you say that if a steel building is never used, it will stay up forever?

kghost · « **Reply #31 on:** August 07, 2005, 06:06:26 PM »

Course not. Outside stimulus will make it fail sometime. Wind, Corrosion, Earth movement, etc.

Sorry Buddy, Bull#$%* says I.

When I went to engineering school, Fatigue was defined as being caused by an outside influence.
Trying to say that the chain will fatigue by only hanging on the sprocket due to gravity gave my engineer friends a good laugh.

Yeah, me too. In fact, so would anybody who has had the least amount of training or experience in metalurgy or physics.
Gravity, as a causal isolated stimulus, may indeed have a fatiguing effect on alloyed metals. However, the delta T of such an effect would be measured in increments of "ages".
A being that witnessed such an event, would far exceed the normal human lifespan experienced on this earth. Few have come forward thus far to share such an event. In fact, only one that I have heard of...

Gentleman, this can obviously be setted only one way...The only way true gentleman can settle any dispute....

Good for me.

It is not like I am saying you have to believe me. Just saying what I DID see. You must remember that there are different types of steel, iron, ect. All which have different properties. Some are more susceptible to fatigue than others. You CAN ask people who know metalurgy and fatigue from weight alone is a big concern. If it were not, things like bracing would not be some important.

But I will end it here. I know what I have seen and been told by others and you know what you know. Simple as that.

The only other thing I can say is to look at a barbed wire fence. They stretch and sag after years even if nothing has pushed against them. Fatigue.

kghost · « **Reply #36 on:** August 07, 2005, 09:57:13 PM »

From Tension on the wire.

Trust me on that one. I've strung miles of fence. (outside Stimulus)

eldar · « **Reply #37 on:** August 08, 2005, 01:16:54 PM »

I must have used a different method of fencing. We used large U shaped staples. It was pulled taught but not tightened. So it was level without excess pulling.

Whatever though. Does not really matter since something like this can only be answered by a metalurgist and even they will probably give different answers.

I would not use an old chain that has been sitting on a bike, period. Just too unsafe because even IF there is no fatigue, there will be weakening from rust and elements. I would rather stop using the brakes and not my head. I dont think anyone would argue against that one.

kghost · « **Reply #38 on:** August 08, 2005, 09:27:45 PM »

Oh yeah, and wind on the fence.

I agree with ya on the last part though. Unless the "old" chain is in a sealed, lubed bag or something why risk it. I would'nt recommend a russty chain to anyone.

78_SaltLick · « **Reply #39 on:** August 08, 2005, 09:30:38 PM »

so do you guys think its worth it to get a sealed chain, or just go with the standard chain. Im about the buy one now, but the price difference is large. I can either go with the standard $60 chain, or go for the sealed one for $100, is it really worth that? I will not be riding my bike in the rain, and really dont plan on any super long road trips, just your standard around town and to work once a week bike. Whats your opinions.

kghost · « **Reply #40 on:** August 08, 2005, 09:38:36 PM »

Sealed o-ring chains tend to wear longer than standard chains.

Its a function of the o-rings holding lubrication within the pivot links of the chain while keeping dirt/debris out.

That being said if you are religious or anal about cleaning and lubing a standard chain it will give good service.

Buffo · « **Reply #41 on:** August 08, 2005, 09:41:31 PM »

sealed o-ring chains last far longer than standard chains and x-ring chains last longer still...under normal conditions. what ever that means. I use sealed o-ring chains. if you ride in the rain or not crap will get on your chain and without the sealing rings it gets in the chain. well a lot more of it anyway. in my opinoin I cant see any reason to get a standard chain over a o-ring chain except you cant afford the xtra $$$.

i am sure someone else here will give you the flip side of the question but thats my 2 cents

Don

kghost · « **Reply #42 on:** August 08, 2005, 09:43:50 PM »

You could probably make a non o-ring chain last as long as an o-ring one.

If you cleaned it every day!

Oh, yeah and turn it upside down every 12 hrs. to counteract the gravity.

eldar · « **Reply #43 on:** August 08, 2005, 10:12:42 PM »

not every twelve hours. only every couple days or so! The sprockets should be flipped too since they might bend if you take too many corners......... If I saw that, I think I would stop riding!

dieselbenz · « **Reply #44 on:** August 09, 2005, 05:21:23 PM »

I forget now what my original question even was.

Oh, yea, I remember. Anyone know how I can retrofit shaft drive onto a 72 CB-500K?

eldar · « **Reply #45 on:** August 09, 2005, 05:25:27 PM »

Do you want it to work? If not use the big hammer technique!

TwoTired · « **Reply #46 on:** August 09, 2005, 05:46:49 PM »

Yeah I wanted a shaft drive, too.
The way I did it was to acquire the shaft drive unit from a 79 CX500 (it was free). Then I fixed the starter, then the carbs had to be cleaned - twice, then the gas tank had to be cleaned, then the front brake caliper and master cylinder, then the muffler system and seat, then the thermostat and radiator flush, then the v reg for the temp guage replaced, when I determined that it really wasn't overheating after all. A little paint and its ready to ride.
The amazing part is that when it's all done, I think it's going to look just like a 79 CX500D.

Like this?

Buffo · « **Reply #48 on:** August 09, 2005, 06:39:52 PM »

Why on earth would you want to ruin a perfectly good motorcycle by putting a shaft on it??? BMW is, I think, the only company who makes a shaft driven bike that is great working...unless you a wizz of an engineer I dont recomend that you undertake that task. In all reality it will not end up like you wish.

kghost · « **Reply #49 on:** August 09, 2005, 06:47:08 PM »

Works good on a touring bike.

Makes the chassis a tad twitchy in the corners with throttle movement.

Works ok on my 78 Goldwing.
